Looking for advice on a jewelry box that I am making. I spent big bucks and bought the “Brusso” hinges! I routed the mortises and attached the hinges. The lid will not close unless it’s pressed down, and springs up 1/4” when not forced down.

My mortises are just a hair (maybe a 1/64”) deep, on all 4 mortises. Would this be the cause of the problem???

Thanks Ike. The hinges slide into the mortises fine. There is even a little “slop” which I’m wondering if I should get rid of by sanding the lid and box with some 180 or 220 grit taped to a flat surface…

Let me clarify my original post. The mortises are about 1/64” too deep, so the hinge is sitting down just a hair.
